Dynamic Stability Control (DSC) The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions (un-
dersteering or oversteering, for example)
and holds the vehicle on a sure course
by intervening via the engine and by
braking intervention at the individual
wheels.
The system activates automatically each
time you start the engine.462us284
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is actively regulating drive
torque in response to monitored vehicle
operating conditions.
If the indicator lamp fails to go out after
the engine is started, or comes on dur-
ing the course of normal vehicle opera-
tion:
If the system was not switched off,
there is a system malfunction. The vehi-
cle remains operational, but without
DSC. Please consult your BMW center
for repairs.
To deactivate the systemPress the button. The indicator lamp
flashes.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In exceptional instances, it is effective
to deactivate the system:
>when rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 110.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. For this
reason, do not take risks by using the
additional safety margin provided by
the system as an excuse.<
For additional details concerning DSC,
please refer to the chapter describing
"Advanced technology" on page 163.

Automatic climate control Air supply

By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control of the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: The
blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button of the automatic
climate control.
To defrost the windshield and
side windows
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Switch off the air conditioner at outside
temperatures below approx. 42 7
(5 6). This will help to prevent the win-
dows from fogging up.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic recirculated air control
(AUC)
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then recirculates the air already within
the vehicle. By repeated actuation of
the button, you can select one of three
different operation modes.
>Indicator lamps off: Fresh air flows
into the vehicle
>Left-hand indicator lamp on Ð AUC
mode: The system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air already within the
vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle.
>Right-hand indicator lamp on: The
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply as
required.<
